Engineering Mechanics - Dynamics Chapter 12 ra θ = r' a ' = r'' a '' = v r r' = v r 1.2 m s = v r ' = v 1.257 m s = a r r'' r ' 2 = a r 0.57 m s 2 = a r '' 2 r' ' + = a 10.551 m s 2 = Problem 12-149 The slotted link is pinned at O , and as a result of the constant angular velocity ' it drives the peg P for a short distance along the spiral guide r = a where θ is in radians. Determine the velocity and acceleration of the particle at the instant it leaves the slot in the link, i.e., when r = b. Given: ' 3 rad s = a 0.4 m = b 0.5 m = Solution: b a = = r' a ' = r'' 0 m s 2 = v r r' = v r ' = a r r'' r ' 2 = a 2 r'
